OBI-M2

Compact and Rugged Combustion Analysis System for use on Vehicles, Motorbikes and Test Benches

OBI-M2 is our most compact on-board combustion analysis system implemented on MIRACLE2. It is an extremely compact and fully featured combustion analysis system suitable for use on test benches and on-board, tested and validated in the most demanding racing world.It can be connected to standard crankshaft position sensors, without any crank angle adapter needed. Optional integrated charge amplifier Champion for piezoelectric pressure sensors.

When connected to the application engineer’s laptop, OBI-M2 user interface allows real-time streaming of cylinder pressure signals over ethernet and high speed data acquisition for post-processing view and analysis.Among its several usage patterns, OBI-M2 can be used to develop and optimize the engine calibration both on the test bench and on-board, thanks to the additional information regarding combustion. It is also a monitoring system, as OBI-M2 detects any limit value violations defined by user and saves the raw data along with a pre-event and post-event history. Alternatively, OBI-M2 is very well suited for combustion analysis and control in vehicles or motorbikes as a standalone system, thanks to its 32 GB on-board data storage.
